Hi okieseeker, deleting your backup and recreating it is probably the easiest option, but if you don't want to delete it, you can also just remove individual files from your backup set to make it smaller. If you want to do that, it is a two step process. Part 1 is exclude the file from the backup set, and part two is to remove the file from the backup location.
Part 1: Go to the backup window and click the "Preview" button at the bottom. Check the files you want to exclude from the backup set. Then, once you have checked all the files you want to remove, click the link at the bottom that says "Remove from backup set". This tells Norton 360 not to copy those files over to the backup location on your D: drive when you run backup. However, it does not delete the large files that are already in your backup. Thus,
Part 2: Now go to the "Where" tab in the backup window and click the "Delete backed up files..." link. Now in this window, you can select the files you want to delete from the backup set to make its size smaller.
So, with those two steps you can delete the large files from the backup set and prevent them from being added again when you run backup in the future.
